Estimation ff the Global Root Mean Square Error of Geoid Height Calculated by Integral Transforms
Belinger, Jiří ; Pitoňák, Martin ; Trnka, Petr ; Novák, Pavel ; Šprlák, Michal
Integral transformations of the gravitational field gradients are defined over the entire solid angle on the surface of the sphere. Despite the indisputable progress in satellite gravimetry and gradiometry, gravity field focused satellite missions allow accurate determination of the gravity field with a spatial resolution of 100 km, i.e. only in its long-wavelength part. However, there is also a need for high-resolution gravity field models at regional, national or continental scales, especially concerning the determination of the quasi-geoid or geoid. On the other hand, potential weakness of ground-based data is the long-wavelength gravity field accuracy and limited availability due to several constraints (e.g. deserts, lakes and large rivers, forests, or lack of goodwill between neighboring countries to share sensitive data). The ideal scenario combines ground and satellite data that complement each other. In this paper, relations defining the estimation of the global root mean square errors of geoid heights using integral transformations will be derived and presented. For practical calculation, knowledge about the accuracy of measured terrestrial data and formal errors of global satellite models of the Earth's gravity field will be utilized.

A New Software For the Calculation of Far–Zone Effects For Spherical Integral
Trnka, Petr ; Pitoňák, Martin ; Belinger, Jiří ; Novák, Pavel ; Šprlák, Michal
Integral transformations are a useful mathematical apparatus for modelling the gravitational field. They represent the mathematical basis for the formulation of integral estimators of gravity field values, including error propagation. One of the basic assumptions of integral transformations is global data coverage. However, the availability of ground measurements is frequently limited. In practice, the global integral is divided into two complementary regions, namely the near and far zones. Non-negligible systematic effects of data in the far zone require accurate evaluation.
For this purpose, a new software library is being created in the MATLAB environment to calculate far-zone effects in integral transformations for gravitational potential gradients up to the third order.

Managerial Competencies in Small Enterprises
Novák, Petr ; Szarková, Miroslava (referee) ; Mohelská, Hana (referee) ; Tomšík, Pavel (referee) ; Putnová, Anna (advisor)
The dissertation thesis dealt with the managerial competencies in the small manufacturing enterprises in the Czech Republic. The research aimed to examine the current level of these competencies on the sample of top managers of those enterprises. The chosen topic is topic of current importance due the competency development for enhancing the managerial performance. The thesis elaboration was based on the detailed literature review of national and international publications in the respected scientific journals, and on the in-depth analyses conducted through the primary researches. The main objective of the dissertation thesis was to detect the competency level of top managers in the small manufacturing enterprises in the context of business management and to identify the key variables influencing the discovered competency level and on the basis of research findings provide recommendations for further competency development. The main objective was supported with four partial objectives and five research hypotheses. On the basis of results of executed pilot research on managerial competencies the model of managerial competencies was established, and further verified in the author’s primary research. Within the data analysis and data evaluation, the competency level was formed. The dependences of competencies on examined variables were tested empirically. Those variables were sex, length of current and total practice, age, ownership and education. The aggregated research results were compared with the literature review and based on this comparison, the recommendations for further managerial competency level improvement were provided. The conclusions and further research aims form the integral part of the dissertation thesis.

Proposal of Communication Plan in Servis GRIMALDI, SPOL. S R. O.
Lukáčová, Zuzana ; Grimová, Lenka (referee) ; Novák, Petr (advisor)
This thesis is focused on suggesting improvements and developments of a mix of communication tools leading to increased number of new customers in the company called Grimaldi spol. s r. o. This is a small company which specializes in exhibitions, interiors, exteriors, furniture and graphic designs. The theoretical part deals with marketing environment, communication with public and mix of communication tools, and is based on available marketing-related literature, marketing communication, and relationships between the company and the public. The analytical part describes an actual situation in this company, evaluates individual communication tools, and also presents marketing research of communication. Results of the research conducted in the analytical part are then given in the third section of the thesis. These results are essential parts of the design for its own amendment proposals and recommendations, and improvements of the current situation in the company.
